I started a stack overflow issue and i was asked to post a bug here:

I have a swing application and inside i added a JFXpanel from javafx2 jdk1.7_17 (also tried 1.7_15). i do create the JFXpanel in EDT and add it on swing tabbed pane, then add the scene to the FXPanel in javaFX thread as shown in the doc. If i run the application once everything is fine, if i stop the application and run it again the jvm crashes saying Problematic Frame libdbus. After closing the application no matter how many times i try the jvm will crash complaining about dbus usually but not always:

JRE version: 7.0_17-b02
Java VM: Java HotSpot(TM) 64-Bit Server VM (23.7-b01 mixed mode linux-amd64 compressed oops)
Problematic frame:
C [libc.so.6+0x12fbd6]Java Result: 134

Sometimes i get this:

 GConf-WARNING **: Got Disconnected from DBus.

If i restart the pc it runs ok the first time again and then if i close / re-run it keeps crashing at start up. I am running fedora 18 and i believe it maybe OS related since java FX is using native libs.
